Pros

Cons

The Deskstar 5K3000, released by Hitachi alongside the 7K3000 in late 2010, is a family of high-capacity internal hard drives for desktops. Targeted primarily at OEMs, the drive will be available in capacities of 1.5TB, 2TB, and 3TB. The 5400RPM drives are not as fast as the 7200RPM 7K3000 models, but will consume less energy and operate more quietly. They utilize Hitachi's CoolSpin technology to optimize performance and energy efficiency. Specifically, Hitachi claims they use 29% less power and make 14% less noise than their 7K3000 versions. Buyers considering the 3TB model should be aware of the 2.2TB storage limit on 32-bit PCs.
